3.3.1 Case Option

[1]
list
'Using the option "..." tokens and phrases ...'
    Insert comma before "tokens".

[2]
"The following table summarizes the interactions between the case match
options and the use of the default collation."
    I think you need a preceding intro sentence, something like:
        Matching is also affected by the query's default collation (see
        section 2.1.1 and 4.4 in XQuery spec).

Case Matrix
    [3a]
    This table is somewhat confusing. It would help to use <th> elements
    (assuming they are rendered distinctively).

    [3b]
    Also, the upper-left cell
        "Default collation options/Case options"
    should I think be
        "case option \ default collation option "
    (See "S\T" in the F+O spec.)
    Or, more clearly, "case option" could be put in a rowspan=4 cell to
    the left of the case options, and "default collation option" could be
    put in a colspan=3 cell above the collation choices.

    [3c]
    Also, you need to explain what "lowercase(Expr) + UCC" (etc) means.
